Explanation:
Iron is found in hematite, an ore with the formula Fe₂O₃.
It goes into a blast furnace, where burning coke and a forced supply of air react to form mostly carbon monoxide.
C + O₂ ⟶ CO₂
C + CO₂ ⟶ 2CO
At the high temperatures inside the furnace, the carbon monoxide reduces the hematite to liquid iron.
Fe₂O₃ + 3CO ⟶ 2Fe + 3CO₂
The iron flows to the bottom of the furnace, where it is drawn off.

Answer:
<em>20 Liters</em>
Explanation:
If the pressure is supposed to be constant, one of Charles - Gay Lussac's laws can be used to solve the exercise. His statement says that "the volume of the gas is directly proportional to its temperature at constant pressure", mathematically it would be:
Considering T₁ = 50 ° C; V₁ = 10.0 L; and T₂ = 100 ° C, we can calculate the volume V₂ Clearing it from the equation and replacing the values to perform the calculation:
V2= (V1 x T2) / T1 = (10.0 L x 100°C) / 50 °C = 20 L
Therefore, <em>the gas at 100 ° C will occupy a volume of 20.0 L</em>.
